What is mailcow?
mailcow's release notes are almost entirely upstream security currency.
mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.
What is Chatwoot?
Chatwoot is building an AI-first support platform, with Captain gaining audience targeting and macro automation reaching the keyboard-native workflow.
Chatwoot has moved decisively beyond multi-channel inbox. Voice calling launched in June, followed by a dedicated calls dashboard in August. The Captain AI assistant now handles configurable audience segments and schedule windows, and generates FAQ suggestions from resolved conversations. The Help Center gained a proper editorial draft workflow. The pace of major feature additions — at least two sparks in six weeks — signals a product that is shipping aggressively toward a full customer support OS.
mailcow vs Chatwoot: editorial side-by-side
mailcow
5.0COMMS
mailcow's release notes are almost entirely upstream security currency.
◆ Current state
mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.
◆ Where it's heading
For a self-hosted mail stack that bundles a dozen upstream components, keeping current with their CVEs is the product, and mailcow has organized its release cadence around exactly that. The pattern is consistent: a named release with some feature content every few months, then lettered revisions that are pure security currency plus small web UI escaping and validation fixes. The web interface is where mailcow's own code gets hardened - HTML escaping in quarantine views and sieve editors recurs across several revisions.
◆ Prediction
Expect the next entry to be another lettered revision carrying upstream updates, with the next named release likely bundling whatever feature work has accumulated since March.
Chatwoot
7.5COMMS
Chatwoot is building an AI-first support platform, with Captain gaining audience targeting and macro automation reaching the keyboard-native workflow.
◆ Current state
Chatwoot has moved decisively beyond multi-channel inbox. Voice calling launched in June, followed by a dedicated calls dashboard in August. The Captain AI assistant now handles configurable audience segments and schedule windows, and generates FAQ suggestions from resolved conversations. The Help Center gained a proper editorial draft workflow. The pace of major feature additions — at least two sparks in six weeks — signals a product that is shipping aggressively toward a full customer support OS.
◆ Where it's heading
The Captain AI thread is the most directionally significant. Audience targeting, scheduling, reasoning transparency, self-generated FAQs, and performance metrics together sketch a product vision where support teams supervise AI rather than do first-contact response. WhatsApp integration is being fortified in parallel — BSUID support, guided setup, centralized templates — suggesting that WhatsApp is the primary channel driver for Chatwoot's growth. Voice calling is being hardened one release cycle after launch.
◆ Prediction
Captain will get more sophisticated handoff logic and routing controls. WhatsApp integration will likely expand to Business Calling or catalog features as Meta expands access. Voice calling will get queue-based routing and richer SLA integration.
